AR15/M16 Rifle Variant Bolt Cleaning and Polishing Tool

Abstract

An AR-15 / M-16 rifle variant bolt cleaning and polishing tool comprising three pieces designed for scraping the carbon build up off of a dirty AR-15 / M-16 rifle variant bolt, then polishing the residual carbon completely off the bolt tail. The scraping is accomplished by means of a scraping blade with a radius that matches the bolt tail and rotating the bolt tail against this blade while applying pressure. The polishing is accomplished by inserting a scouring pad between the polishing arm and the main body of the tool and then applying pressure to the polishing arm creating torque to polish off residual carbon.

Description

CROSS REFERENCE[0001]The present application claims priority from provisional patent application 61 / 241,495, filed on Sep. 11, 2009 the contents of which are incorporated by reference in their entirety.BACKGROUND OF THE INVENTION[0002]1. Field of Endeavor[0003]The present disclosure relates to the cleaning of the bolt used in semi-automatic and fully automatic rifle variants such as those rifles styled after the direct gas impingement of the AR-15 or M-16 rifle.[0004]2. Description of the Prior Art[0005]The function of the AR-15 / M-16 rifle and its variants utilizes a method of direct gas impingement where the expended gas of a fired cartridge is captured and funneled back into the rifle to complete the cycle of operation. By doing so, gas is directed onto the bolt tail where carbon from the gas accumulates. This carbon builds as the rifle is repeatedly fired and can cause stoppages and malfunctions within the rifle and the cycle of operation if not cleaned from the bolt tail.[0006]O...

AI Technical Summary

Benefits of technology

"The present invention is a tool for cleaning and polishing automatic and semi-automatic rifles. It is designed to be easy to use with a comfortable fit in one hand. It has a pivot arm that provides enough torque to effectively clean the rifle. The tool is made for durability and resistance to chemical solvents. It has a laser-cut scraper blade that removes carbon build-up from the bolt tail in seconds. The unique polisher ensures that the carbon on the bolt tail is removed and helps prevent residual build-up on the bolt tail."

Problems solved by technology

This carbon builds as the rifle is repeatedly fired and can cause stoppages and malfunctions within the rifle and the cycle of operation if not cleaned from the bolt tail.

Other methods for cleaning this carbon from the bolt tail are generally ineffective, time consuming and laborious, and include wiping with a cloth, the use of chemical solvents, scraping with non-specific tools such as screwdrivers, knives, dental picks, and expended cartridge casings.

Further, none of these methods completely remove the carbon from the bolt tail.

U.S. Pat. No. 7,644,529 B2 to Hopper et al. issued Jan. 12, 2010 describes a simplified tool that scrapes a portion of the carbon off the rifle bolt tail, but does not completely remove the carbon from the rifle bolt tail or assist in the continued maintenance and future cleanings by removing all of the carbon from the rifle bolt tail thus limiting the carbon build up.
